Cellulase, a multi component enzyme, is the most widely used enzyme in food processing, paper and textile industry. Cellulase enzyme has gained more importance in bio-ethanol production, due to the wide application of cellulose in variose industries it is necessary to produce cellulose in large amounts. In earlier days chemical process were adopted in industries but the search has turned into more environment friendly processes since the chemical process causes severe health hazards and detoriation of the environment Hence the industries are trying to replace these chemical processes by enzymes.
But the cost of production of the enzymes is high due to the expensive raw materials, low yield of the product enzymes and the cost involved is its purification hence the key in the reduction of the enzymes production cost is to increase the yield and move on to cheaper and easily available raw material. Since cellulose is an inducible enzyme high yields are obtained only when substrates containing large amount of cellulose are used.
In our experiment production of cellulose is carried out on rice husk as substrate using the strain Aspergillus niger. Rice husk is chosen as substrate due to high content of cellulose low and easy availability. Experimental work shows high growth rate and high yield of cellulose by Aspergillus niger of rice husk
